1. The IBM Power Systems Performance Advisor plug-in The IBM Power Systems Performance Advisor (PPA) plug-in allow s users to profile C/C++ applications based on a select ed set of processor-specific metrics. PPA leverages Ocount , an Oprofile tool used to count native hardware events, to gather the processor performance data and calculate the metrics. The IBM SDK for Linux on Power (SDK) 1.10 provides a new version of the PPA plug-in. This version provides visualization charts for metrics and also includes a d r... [More]

Using Advance Toolchain on SDK The IBM SDK for Linux on Power (SDK) 1.10 provides support for Advance Toolchain 10.0 (besides 9.0 AT version). In the following we will show you how you can use SDK togheter Advance Toolchain. 1. Installing AT packages You can install AT packages for 10.0 and 9.0 versions. Those packages are allowed on ftp://ftp.unicamp.br/pub/linuxpatch/toolchain/at site. Choose Linux distro you are using (RHEL, Suse, Ubuntu, etc). Then select packages the following packages (rpm or... [More]

My new blog entry: Enable System Native BLAS library for netlib-java on OpenPOWER Linux Systems on the Linux on IBM Power Systems Developer portal provides instructions on enabling a System Native BLAS library for netlib-java on OpenPOWER Linux distributions, such as Red Hat Enterprise Linux 7.2 (little-endian) and subsequent releases.

I am pleased to announce a major update to the deep learning frameworks available for OpenPOWER as software “distros” (distributions) that are as easily installable as ever using the Ubuntu system installer. Significant updates to Key Deep Learning Frameworks on OpenPOWER Building on the great response to our first release of the Deep Learning Frameworks, we have made significant updates by refreshing all the available frameworks now available on OpenPOWER as pre-built binaries optimized for GPU acceleration: Caffe , a...

This release provides many package updates, including: GCC 6.2 Glibc 2.24 Binutils 2.27 GDB 7.11 Support for Ubuntu 16.04. GCC provides fixes for complex IEEE 128-bit floating point and support for IEEE 128-bit floating point built-ins. GCC creates binaries using --mcpu=power8 --mtune=power8 by default on ppc64le. Valgrind provides a fix for missing support for wbit field on mtfsfi instruction . Valgrind Itrace provides a new option to... [More]

Recently saw some email exchanges around a team porting a software package which used the Intel SSSE3 instruction set ( https://en.wikipedia.org/wiki/SSSE3 ). New users to Power8 may not know where processor and instruction sets are documented for the POWER architecture. OpenPower and Power.org are good places to find the "ISA" documentation (the instruction set architecture) for POWER. Some people may call this type of document a "compiler writers reference". Naturally, this ISA document is... [More]
